Shenzhen Zhongnuo Testing Technology Co., Ltd. offers on-site explosion-proof electrical inspection, explosion-proof project acceptance services, and consulting services. Additionally, we provide explosion-proof rectification and construction services for items that fail inspection.
How often should explosion-proof electrical equipment be inspected? How to apply for an explosion-proof electrical inspection report?
Should explosion-proof electrical equipment in use be inspected regularly? How often should a check report be generated? What standards are specified, and how are they defined? These are questions that many industrial clients with explosive hazards, such as chemical, grain and oil, and gas station owners, are eager to know. Zhongnuo Testing will simply answer these questions for you.
Due to the industry's特殊性, facilities with explosive hazards must purchase and install equipment with a valid explosion-proof certification, and ensure proper installation and maintenance. In addition, regular safety inspections and routine maintenance of these electrical equipment must be conducted to confirm their continued explosion-proof performance. The AQ3009-2007 "Electrical Explosion-Proof Safety Regulations for Hazardous Areas" also stipulates that regular inspections should be carried out by safety inspection and testing institutions with explosion-proof qualifications, with intervals generally not exceeding 3 years.
ZhongNuo Inspection has provided on-site explosion-proof inspections and reconstruction services for various facilities such as gas stations, oil depots, food factories, feed mills, and chemical plants, boasting a substantial number of successful cases and industry experience.
